In 1960 my age was equal to the digits sum of the year of my birth. What is my age now?

Correct result:

n =  78



The equations have the following integer solutions:
a = 1+9+c+d
1960 - (1900+c*10+d) = a

Number of solutions found: 1
a1=17, c1=4, d1=3

Calculated by our Diofant problems and integer equations.
